How NAC 800 Handles Static IP
Addresses
The following list details how NAC 800 handles static IP addresses:
■ Inline Mode – NAC 800 can detect, test, and quarantine static IP
addresses. The end-user cannot circumvent a quarantine.
■
DHCP mode
• NAC 800 can detect and test static IP addresses but cannot quarantine
static IP addresses.
• NAC 800 can detect static IP endpoints in two different ways:
–
Any type of traffic from the endpoint can be detected if that
endpoint has any network traffic visible by NAC 800
– By using the Agent Callback feature (see “Agent Callback” on
page 5-3).
• An endpoint with a static IP address can be automatically tested only
if the endpoint:
–
Has credentials stored for agentless testing.
– Already has the agent installed.
If you do not use the items in the previous list, you cannot capture the users
attention in their browser to force them to supply credentials or install an
agent and get tested.
• If an endpoint has a static IP address and it can’t be tested automati-
cally, the endpoint shows up as
awaiting test initiation in the Endpoint
activity window.
■
Any mode – An administrator can manually test any endpoint by
pointing the endpoint’s browser to
http://NAC 800 Enforcement
server IP address>:88.
This includes endpoints with static IP
addresses.
